STEAM LOCOMOTIVE.

Application nled June 30, 1927. Serial No. 202,572.

My invention relates to improvements in `steam locomotives and iced-water heaters 'l therefor, although the invention is applicable also to steam engines of other types.

means for utilizing exhaust steam for eiecting a preliminary heating oi' the feed water, such exhaust steam being so directed that it will not only .facilitate the draft through the i'ire box, but will be muled to a,considerable extent, thereby reducing the exhaust sound ordinarily present-in locomotives and other steam engines.

My invention has for one of its objects the provision of an improved means for heating feed water.`

` Another object of my invention is to deaden the sound of the locomotive exhaust and to educe the vvolume ofvsmoke and'exhaust gases that ordinarily issue from-the stack. V

One4 form which my invention may take j is shown in the accompanying drawing,

wherein Figure 1l is a longitudinal sectional view. of a portion of the locomotive, and

. 'I type,

smoke box 4 anda series of arch tubes 5 that Fig. 2 is a view taken on the line II--II of Figi. Y

The locomotive is of somewhat the usual being provided with a fire box 3, a

' is formed by concentric tubes 8 and 9. Pack- 'ing rings 10'and 11 are provided at the front and rear ends respectively of the tubes 8 and 9, so as to close the ends of the space 7 between such tubes.

"A steam exhaust pipe 12, which is connectedto the locomotive cylinders has connection with the interior of the tube 9 s Broadly stated, my invention comprises chamber 13. 'From the compartment 16, the water will flow through pipes 17 and 18 that have connection with the re tubes 5, there being as many pipes 17 and 4'118 as desired, dependingv somew-at upon the size of the compartment 16.

As the water flows through the passage 7, it will be heated by the exhaust steam and a saving in fuel thereb effected.' The provision of pipes 17 an 18 at diierent levels permits of circulation of waterk through the compartment 16 when; no water is flowing into the locomotive through the pipe 6, thus preventing over-heating of such -compartment.

The arrangement of the tubes 8 and 9 and -the chamber 13 is such that the apparatus can be installed in existin types of locomotives, without material y altering the structure of the locomotives, by'reas'on of the fact that the said tubes can be inserted in the space normally occupied by some of the fire tubes, and the chamber 13 can be placed in the space usually found above the arch, and

can`be conveniently removed and applied.

'At the upper end of the smoke box 4 I provide a fan 20 driven-from any suitablesource of power (not shown), as a steam turbine, that serves to draw the heavier particles from the exhaust gases and direct them, through a conduit 21 to the space 22 beneath the grates.

The amount of smoke and solids I deiiected by the fan 20 from the stack is Y greater by reason of the fact that the exhaust steamtends to precipitate or render heavier the solid or semi-so id particles in the exvhaust gases, thus reducing the amountv of that steam will be directed through saidtube.

into a mber 13, the forward wall of which .is provided with' perforations 14 that from the perforations 14 facilitates i the di' aft. Vthen water is being admitted thropgh the injector through tle space 7 an through passages, 15

.may be operated by a iipe '6, it will passA 44and gases from the smokeissuing from the stack andeiecting a saving in fuel, by causingl the defiected material'to be passed throug the fire bed.l Incase it is not desired to pass the smoke pipe 2,1 through the grate, such gases may be deflected byl a threeway valve 21a of any suitable form which n ll rod or link 23 from the locomotive caib. that the smoke and gases will be by-passed through a pipe 24 that leads to the front end of the s mole boxwhere it will be at least partially consumed. v

From' all of` the foregoing, it will be seen that I eect a saving in fuel, througlh heatin of the' feed water with the norma waste eighaust1 steam, and by consuming'productg loo 'I (not shown), so

I smoke toa large degree.

l I claim as my invention 1. The combination with a locomotive, of a feed water heater therefor, comprising a steam exhaust pipe leading rearwardly through the boiler and having openings at its rear end .to permit exhaust to the locomotive stack, a passage surrounding said pipe, a water inlet pipeconnected to said passage at one end, and a. connection between said passage and the water spacel in the boiler at its other end. 2. The combination with a locomotive having a fire box, fire tubes and a stack, of a steam exhaust pipe leadin rearwardly from a point adjacent to the ront end of said tubes to the fire box, a lpassage-way surrounding saidh pipe,y means for `directing' feed water into one end of said passageway, and means permitting vflow of said water fromthe other en d of said passage-way. 3. The combination with a locomotive having a fire box, `fire tubes, and a stack, .of a steam exhaust pipe leading rearwardly from a point adjacent to the front end of said tubes to the fire box, a passage-way surrounding said .pipe, means for directing.

feed water into one endeof said passageway, means permitting iow of said water from the other end .of said passageway, and

- means for directing the exhaust steam forwardly from said re box, through the fire tubes. .Y

ei. The combination with a locomotive having ire tubes, a fire box, and arch tubes,

0f a steam exhaust pipe leading rearwardly from the front end of said tubes, a chamber connected to the rear yend of said plpe and 'compartment 'and the having forwardly extending perforations, a

inlet pipe connected to theV forward end of vthe passageway, a connection between the rear end of the passage-way and said compartment, and a connection between said boiler.

'5. The -combination with a locomotivel .water space in the having re tubes, a lire box, and arch tubes,

of a steam exhaust pipe leading rearwardly from the front end of said tubes, a. chamber connected to the rear end of said pipe and having forwardly extending erforations, a passageway surrounding sai pipe, acompartment surrounding said chamber, a water inlet. pipe connected-to .the forward end of the passageway, a connection betweenthe rear end of the passageway and said compartment and connections between said coml partment and the arch tubes.

6. The ,combination with a locomotive having fire tubes, a fire box, and ,arch tubes, of a steam exhaust pipe leading rearwardly from the front endA of said tubes, a chamber connected 'to the rear end ofsaid pipe and having forwardly extending perforations, a passageway `surroundilig said pipe, a.com partment surrounding said chamber, a water linlet pipe connected to the forward end of the passageway, a connection between the rearend of the passage-way and said compartment, and a connection between the upper and lower portions of said compartment and the water space in the boiler.

In testimony whereof I, the said MICHAEL Pnmcmhave hereunto set my hand.
